,To all urlmm it may concern:

Be it. known that I, LAWRENCE HAYES, u. resident of Monong'uliela, in the county of lV'nsliington and State of Pennsylvaniamve inwntod. certain new` and 'useful Improveinonts in Vehicle-Springs, of which the fol lowing is a, specification.

My invention relates to suspension springs for uutonu'ibiles and other Vehicles and its objects :1re to provide a simple and efective devine capable of withstanding sudden and violent shocks, being interposed between the running: gear and body portions of a Vehicle in suoli nuinner as to absorb and prevent t1-nn :nii-.ion to tbe body of any severe jur or Yiln'utiou to which the running gear muy be subjected.

)t further purpose is to provide means which udjxnit of tbe employment oi e 'plu-- relity of points of suspension for tl'i'ebody upon tbe spring-ineinbers, and to provide ineens for interposing e Varying resistance between the main spring und body of tbe Vehicle of ueli a character as to admit of its beine',` readily placed in position when the tiene@ ie ussenil'iled, or easily applied to the eon'nnon :torn-ie of seiniielliptio springe ulreudy in use.

A desirable embodiment of the invention is: illiifdrated by tbe accompanying dra.7- ings, Wbereinllin'ure l4 is u Side elevation of a portion of tbe running geur and body of an entornobile boring my invention applied thereto.

Fig Q a, ,vertice-l. crosse Section ot' a` portion of the device, on un enlarged seule, taken on lii'ieQ---Q of l. Fig. 3, is e. similiar View taken nn line 33-of Fig. 1. Figs= if und ,5 are Side elevations of the mein and Supplemental springs, illustrating n'iodilien@ tiene in the construction of'tbe Su] iplenientul epringg to permit. of ite being'- reudily nl plied 'to the oonnnon forms or' senii-ellintlo .sp-rings. i

.AS shown in tbe accompanying drawings, my device consists oi u moin sel'nifelliptic leal spring 2, which is su'miorted upon the axle ffl, being' Secured by clip 4, or in any A t the outer endv of s'l'iring 2 is bearingl 5 for the reception of a pivot pin 6, by Ineens of which it is secured to tlie outer end of the main frame-7 of the body portion, audits'nner or oppoeite nd is'l formed with a vsimilar bearing '8 for the' 4reoeptifm of a. pin 9, in the lowerend of a;

link l0, the latterl pivoted at its upper end to the vehicle frame 7 in the usual manner.

A supplemental quarter-elliptic leaf Spring 11 is interposed between the main Spring' 2 and freine 7, and is pivotally con# nested at its outer or lower end l2 to the main Spring, approximately midway :be--

and 8, 'thereby insuring a more advuntzigeons distribution of Weight upon. the spring ineinbers, and in addition thereto tbe supplemental Spring 1l, will by reason oi its rel tive location between, and' method of attachment to, the body member 7 und .inain spring 2, oder a Varying resistance to the action o Said main Spring, of sutlieient force to .prevent the latter from recoiling or reexing with suoli violence as to be injured or broken when eubjerted to n severe shock.

ln luy preferred construction, as illustrated in Fig', l., the upper'leuf A. of the' main. Spring 2 atlapted to be pivotully oonneoted et its opposite ends to the link and lower end of bottoni leef C oi the supple` mental Spring 1l, und the next adjacent lout l of the springs extended outwardly u suli'ioient ydirstanee beyond the juncture ol springs 2 und 11, .to be pivotnlly connected :it C to tbe outer end ot. freine 7. ln order tlmt tbe suliiplen'ientiil spring ll niziy be upplied to the ordinary torino of Semi-elliptic Springs already in une, it may be nivotully connected to one end of i1 longr leaf l), adapt ed 'to be Secured to the niuin Spring 2 by menus of :i clip l5, :is shown in Fig', 4, or in any other suitable lnnnner, or it may be. pivotnlly Connected directly to mid main spring by a. (flip 16, :is shown in Fig. 5. The nmin and nupplenion(nl springs may be Composed ol :luy desired number of leuven l'ieldto- `other in may suiublo nninner und the reliutive poeitione ol' tlionivotul connection (S and link ronneetion il() umy be reversed Without departing' from the invention. The usual practice is to pivotnlly connect one end of the main spring directly to the frame, as at 6, and its opposite end by link 10. The pivi etal connection G may be at the outer .eX- tremity of the frame, as here shown, or the arrangement may be reversed. But howvever arranged, I prefer to extend the supspring having load connections at its ends,4

and a quarter elliptic supplemental spring downwardly bowed with its lower extremity pivotally connected to the main spring between the center and one end of the latter and with its upper end adapted to be secured to the load intermediate the extremities of the main spring.

2. The combination of a centrally su ported semi-elliptic main spring, a bo y member having a direct pivotal connection with one end of the main spring, a link pro viding a swinging connection between the body member and the other .end of the spring, and a quarter-elliptic supplemental spring secured at one end to the body Vmeniber between the ends of the main spring..

said supplemental spring extending toward that end of the main spring having direct pivotal connection with the body member and pivotally secured to ,the main spring intermediate 'said end of the latter and the main spring support.

3. The Combination of a semi-elliptic main spring having load connections at its ends, spring supporting means, and a quarterelliptic supplemental spring having one end secured to the main springl intermediate one end oi' the latter and the pointl of support ot the main spring, the opposite end of the supplemental spring secured to the load intermediate the connections between the load and the main spring extremities.

4. The combination of a semi-elliptic main spring having load connections at its ends, spring supporting means, and a quarter-elliptic. spring formed of a plurality of the other at the upper end of said spring with means securing said spring end to the load intermediate the main spring extremities, the lowermost and longest leaf of the supplemental spring having its lower eX- tremity pivotally connected to the main spring inwardly from one end of the latter.

5. The combination ot' a main spring composed of a plurality of leaves, the leaf hay'i ing the greatest extension :1tone end of the spring terminating short ofthe oppofte extremity of the spring and providing a bearing, anda relatively slmrt/snpplemental leaf spring at one end seeured tosaid bearing with its opposite end and the extremities of the main spring secured "to the load.

In testimony whereof I affix my signature in presence of two Witnesses.
